SPECIFICATION forming part of Letters Patent No. 309,169, dated December 9, 18534.

Application filed April Q1, 1F94.

T0 all who/it if; may concern:

Beit knownthat l, WILLIAM STAMP, olSusquehanna Depot, in thecounty of Susquehanna and State of Pennsylvania, have invented 5 a new and useful Improvement in Gar-Couplings, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming partofthis specification,

1o in which similar letters of referenceindieaie corresponding parts in all the figures.

Figure lis a sectional side elevation of my improved car-coupling, taken through the line e, Fig. 2. Fig. 2 is a front elevation ot' one I 5 part ofthe same,the coupling-link being shown in section. Fig. 3 is a sectional plan view of the same, taken through the line as x', Fig. 2. Fig. 4tis a sectional side elevation ot' a part of the saine, taken through theline g/y, Fig. 2.

rllhe object of this invention is to facilitate the coupling and uncoupling ofcars in making up and breaking trains, and promote convenience and safety in said operations.

rihe invention consists in the construction 25 and arrangement of parts, as will be hereinalter fully described and claimed.

A represents the d raw-head of t-he couplin the draw bar or body B of which is connected with the car-body G in the ordinary manner.

3o rEhe draw-bar B is designed to be made of wrought-irc n, and to have the draw-head A cast upon its forward end. The mouth D of the draw-head A is madehopper-shaped to guide an entering link, E, into place, and -is made 35 sufficiently large to allow the interior separable parts of the coupling to be put in andtaken out through the said mouth, so that a broken part can be taken out and replaced by a new part through the said mouth.

W'ithin the draw-head A is formed a large space, F, to .receive the inner end of the link E and the movable arms (hereinafter described) of the coupling, and allow the said parts to have the necessary freedom of move- .4,5` ment. The forward upper part of the space E is curved upon the are of a circle, and the forward side ofthe upper part, G, of the couplingpin is correspondingly curved to provide a firm support for the said part of the pin when 5o sustaining a draft-strain, vand to allow the said part of the pin to move up and down freely.

(No model.)

' Upon the lower part of the forward side ot the part G of the pin is formed ashoulder, I-I, which, when the said part G of the pin is under a draft strain, rests against the draw-head A at the upper side of its throat, to prevent the said part of the pin from rising and releasing the coupling-link E. The upper part, G, of the coupling-pin is formed upon the forward end ot' the arm I, or has a socket in its rear side to receive a head formed upon the said forward end of the arm I. The rear part of the arm I is curved downward,andits rear end is enlarged and has a semi-cylindrical hole, J, formed through it to receive the semi-cylindrical shaft K, which passes through a cylindrical hole, L, in t-he draw-head A. The hole J is made larger than the shaft K, so that the said shaft cau have a slight rotary movement within the said hole. The hole L is made larger than the shaft K, so that the entire (irait-strain will come upon the forward part of the draw-head, and so that the part G ofthe coupling-piu and its arm I can` be pushed back in coupling and uncoupling the cars, to free the shoulder H from the draw-head A, and allow the said part of t-he pin and its arm to rise.

M is the lower stationary part of the coupling-pin, which projects upward and rearward, so as to be met by the upper movable part, G, as shown in Figs. l and 2. The part M of the pin can be formed solid upon the lower part ofthe draw-head A, or it can be made-of wrought-iron or cast-steel and the draw-head A cast upon its lower part, as indicated in dotted lines in Eig. 1.

At the side of the arm I is placed an arm, N, which has a semicircular hole, O, in its rear end to receive and fit upon the shaft K. The arm N is curved forward and downward, and is made ot' such a length that its forward end will rest upon the inner end of the link E. Thelower end,N, of the arm N is ent-ended downward and forward, and passed beneath the end of the link E, and when the arm N is raised the lower end, N', ofthe said arm will raise the said end of the link E above the stationary part M of the coupling-pin, so that the link will be free to draw out when the ears are drawn apart.

To the end ofthe shaft K is attached a crank,

I, the shank of which is made ol' such a length that the arm of the said crank will be about in line with the side of the car-body C, so that the said crank can be operated from the side ofthe track. vWith this construction, by a slight movement of the crank P the outer end of the link E can be raised more or less to guide the said outer end of the link into the `mouth of the draw-head of an adjacent car, the enlarged hole .I in the arm I allowing this to be done without moving the said arm I and the part G ofthe coupling-pin connected with it.` When the ears are run together,the end of the entering link E strikes and slides up the lower stationary part, M, of the coupling-pin, and then strikes the upper movable part, G, of the said pin, pushes it back far enough to free the shoulder H from the drawhead A, and then forces the said part G upward and passes its lower end, the said end of the link E dropping over the said stationary part M of the pin by its own weight, and the said upper part, G, dropping upon the said lower part, M, coupling the ears. The part G of the pin is raised to uncouple the cars by operating the crank I. The outer part ofthe crank Pis supported by a bracket, Q, attached to the carbody,aud which is made with a downward bend, R, to support the crank whenl the parts of the coupling are in a coupled position. rlhe bracket Q is made with ahorizontal bend, S, in its forward part to receive theshank of the crank I). The bend S is made narrow, and the part Pof the shank of the crank that entersthe said bend is flattened to t into the said bend, so as to beheld from turning. The shank of the crank I? is flattened in such a direction that it will enter the bend S only when the crank P has been turned into such a position' as to raise the arm I and part G of the pin into the uncoupled position, where they will be securely held, so that the cars can be run together without coupling.

This improvement is especially convenient in making up trains, as it enables the man making up the train while, the car is passing him to throw the crank P into position to cause the ears to couple, or to remain nncoupled when they are run together.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination, with the draw -head provided with the inclined part M,and therecess F, of the arm I G, formed with the shouldertH on its upper forward end, and apertured at its rear end, and a shaft, K, p ivoted in enlarged bearings L in the draw-head, and passing through thelapertured end of the arm, whereby the arm I may be moved longitudinally until its shoulder is out of contact with the draw-head, and then vertically into the recess F, substantially asset forth.

2. The combination, with the draw-head A, provided with the inclined part M of the arm I G,having an enlarged slot, J at its rear end, the arm N, provided with the forwardly-projectinglower arm,N,and aslot, O, and the shaft K, journaled in the draw-head, and passing through slots J O, said shaft being ofthe same size as the slot O, but smaller than the slot J, whereby the arm N may be operated, as described, without affecting the arm I,for guiding the coupling-link to anotherl draw-head, substantially as set forth.

3. In a car-coupling, the combination, with can be readily set to couple or remain uncoupled when the cars are run together, as set forth.
